Milton Oliver Flower, Coviua, Califi, assignors to Max Factor 82 Co.,Hollywood, Calif, a corporation of Delaware Filed Aug. 14, 1963, Ser.No. 302,070 2 Claims. (Cl. 206-56) This invention relates generally tolipstick holders and more particularly to a holder having a refillcapability wherein a locking member is provided to assure positiveengagement between drive portions of the holder and the refill.

In accordance with the present invention, a lipstick holder has beendevised wherein a ball-in-socket connection is effected between thepomade receptacle and the cup carrier which comprises a portion of thedrive mechanism. In effecting the refill, a new pomade and receptacleare urged longitudinally with respect to the holder proper until theball is received within a cavity within the base of the receptacle.Thereafter, the drive mechanism of the holder may be operated to retractthe pomade into the holder.

The lipstick refill is engaged within its plastic container and duringthe aforementioned retraction it is necessary to withdraw the pomadefrom its container and to overcome the frictional forces between thepomade and the interior of the refill container.

It is a primary feature of the present invention to provide a lockingmember within the base of the refill which will secure the pomade cupand holder drive mechanism in locking engagement prior to withdrawal ofthe pomade from its refill container. The provision of the lockingmember greatly enhances foolproof operation of the refill sequence andin effect makes impossible the disengagement of the respective partswhich may otherwise occur due to the internal frictional forcesattendant upon withdrawal of the lipstick pomade from the refillcontainer.

In the following description reference is made, by way of a non-limitingexample, to one form of construction of a combination holder and lockingdevice devised in accordance with the invention and illustrated in theaccompanying drawing in which:

FIG. 1 is a view showing the relative holder and refill in positionbefore their mutual engagement;

FIG. 2 shows the holder and refill after engagement;

FIG. 3 is a cross section taken in the direction of arrows 33 of FIG. 2;

FIG. 4 is a detail showing the side elevation of portions of the refill,including exterior portions of the locking member; and

FIG. 5 is a detail perspective showing of the locking member.

Referring now to the drawing, reference numeral indicates generally theupper applicator tip portion of a lipstick holder. The holder 10includes an upper casing 11 which includes an inclined applicator tip110 and a collar 11b. A lower casing 12 is disposed below the collar 11bfor free rotation with respect thereto as will be seen. A low pitchedhelically threaded sleeve 13 is frictionally secured to the casing 12.

Coaxially within the members 12, 13, is a hollow inner body 14 which issecured within the collar 11b for common rotation therewith. Within thebody 14 is a carrier 16 having teeth 16a at opposite sides thereof whichextend through diametrically opposed longitudinal slots in the body 14.The teeth 16a are engaged within the helices of the sleeve 13 such thatrelative rotation of the mem- 3,217,869 Patented Nov. 16, 1965 17a andan upper larger cavity 20 wherein the ball may expand to preventdisengagement from the receptacle 18. Preferably the carrier 16a, ball17 and the lipstick receptacle are made of deformable plastic such asnylon to permit the ball 17 to be deformed as it is forced through therestricted passage 19, thereafter assuming its normal expanded shapewithin the cavity 20. Also, the ball will be provided with a slot 17bwhich will assist its deformation, which slot cooperates with thelocking member of the invention as will be described.

The cup 18 contains the base of a lipstick pomade 21 and advantageously,the cup and pomade are packaged for refill purposes within a plasticouter sheath or container 22. The container 22 will have a configuration22a enabling it to be received over the applicator tip of the holderwith the lower edge of the container 22 resting upon the upper end ofthe collar 11b, as shown in FIG. 2.

In accordance with the invention, a locking member 24 is provided withinthe receptacle 18. The member 24 has a button or slide projection 26, aflange 27 and an intermediate groove 25. The slide projection 26 extendsoutwardly of the receptacle wall, the latter having a slot 18a thereinpermitting limited longitudinal travel of the locking member. The flange27 engages and will slide along the internal wall surface of thereceptacle 18 while the slide projection 26 engages the outer wallsurface thereof.

The locking member 24 has a spade-shaped internally projecting end 28which when the slide projection 26 is depressed, may be urged into theslot 17b in the ball 17a. This may be done immediately after theinsertion of the ball 17a into the chamber 20 and will have the effectof expanding the ball 17a sufficiently to prevent withdrawal of the ballfrom the receptacle. It will. be understood that when the drivemechanism is operated to withdraw the pomade 21 from the container 22,frictional forces may be relatively high and the locking member 24 willpositively prevent the disengagement of the respective parts during thisoperation.

Subsequently, when it is desired to replace a depleted lipstick pomade,it is necessary only to elevate the slide projection in the slot 18auntil disengagement of the end 28 of the locking member from the ball17a occurs. Thereafter, with the receptacle 18 in its extended position,the receptacle may be grasped without touching the pomade fordisengagement from the drive mechanism.

It will be appreciated therefore, that the locking member of theinvention enhances and makes positive, the trouble-free operation of theaforedescribed refill process. Since the embodiment presented herein ismerely representative, reference should be made to the appended claimsin order to appreciate fully the spirit and scope of the invention inwhich:

We claim:

1. In a lipstick container having a lipstick holder assembly and alipstick pomade receptacle separably mounted together and drive meanswithin the receptacle holder for axially moving the pomade receptacle,the improvement in combination therewith in connection and locking meansfor selectively maintaining: the holder assembly and lipstick pomadereceptacle operatively connected comprising a ball member extending fromsaid pomade receptacle and operatively connected to said drive means, anarrow slot cut into said ball member, a socket formed on said pomadereceptacle and extending therefrom, said ball member separably heldWithin said socket to join the holder assembly and pomade receptacletogether, and a locking device mounted on said pornade receptacle andhaving an actuable portion positioned externally of said pomadereceptacle and an internal portion positioned Within said pornadereceptacle and dimensioned for tight fitting engagement within saidslot, said locking device mounted on said pomade receptacle to slidefrom a first position wherein said internal portion is separated fromsaid ball member to a second position in locking engagement within theslot in said ball member.

2. A lipstick container according to claim 1 wherein said ball memberand said socket are made of a deformable plastic material.
